CARRIAGE-LAMP.

SPECIFICATION forming part of Letters Patent No. 372,325, dated November1, 1887.

Application filed February 23,1887. Serial No. 228,478.

To aZZ whom it may concern:

Be it known that I, THOMAS PARISH, of Newark, in the county of Essex andState of New Jersey, have invented a certain new and useful Improvementin Carriage-Lanterns, of which the following is a specification.

I adapt a substantial and properly-propoc tioned kerosene-lantern to beattached at will on the dash-board at the front of acarriage, and allowthe entire body of the lamp, oil-pot, burner, reflector, bell, and sidetubes to move up and down relatively to the carriage, or to allow thecarriage to move up and down, according as it may be subjected tovarious jolting niotions,without communicating such mo- 7 tions to thelamp. I provide two sets of springs on each side. The uppermost setsexert a force to lift or support the weightof the lamp.Thelowermostsetsexertaforcetending to depress the lamp or prevent itfrom rising too high under any circumstances. Bothsets are bracedagainst any too great lateral movement. These springs occupy no spacewhich is otherwise valuable. They especially do not necessitate anyincrease in the height of the lantern.

The cheap, familiar, and powerful illuminating-oil known as kerosene hasheretofore been impracticable for carriage-lanterns from its liabilityto be extinguished by-concussions. My experiments indicate that acarriage with at any velocity without extinguishing the flame.

I will describe my invention as being ap' plied to a tubular lantern.

The accompanying drawings form a part of this specification, andrepresent what I consider the best means of carrying out the invention.

Figurel is a front View; Fig. 2, a side view; Fig. 3, a plan view; andFig. 4, a central vertical section, partly in elevation.

Similar letters of reference indicate corre sponding parts in all thefigures where they occur.

her, highly reflective on its inner surface and curved at the rear.Thefront is a plain plate of clear glass. I will term this ordinaryportion of the lamp the body.

E is the bell, which receives the impact of the current of hot gasesfrom the flame, which, dragging with them a supply of fresh air receivedabove the body, rise through the short vertical pipe E, traverselaterally through the crosspipeEfldownward through the side pipes, E andinward through the horizontal pipes E to furnish the air at a pressureslightly above that of the atmosphere to induce the requisite constantand active current to supply the combustion.

M is a casing of metal, adapted to receive easily the curved rear sideof the part D. A wing extending forward at each side is marked M Theentire casing M M is riveted or otherwise firmly secured to a broadclip, L, adapted to fit easily on the dash-board. Through this clip istapped a thumb-screw, N, which, acting through a shoe, 0, enables theclip to take a firm hold oil-the dashboard and to be tightened andreleased at will, preventing at the same time the pressure of screwpointand so injuring the dash-board.

On the exterior of the body D are four'eyes, D D D D one pair on eachside, near the top and bottom. Firmly attached to each wing M is a stoutwire spring, which performs important functions. Each is composed inpart of several coils or convolutions, P, one end of which, P, isextended vertically and soldered or otherwise firmly fixed in theinterior angle of the wing M The other end, P, is extended forwardnearly or quite horizontally, and terminates in a V-shaped hook, P,which isengaged in the upper eye, D, and exerts a lifting force on thelantern. The coils P are braced laterally against each other and againstthe wings Mi so that there is but slight lateral elasticity to thesprings; but they arefree to work vertically to a larger extent. Anotherspring, Q, is mounted in the reverse position on each side, thecorresponding arm, Q reaching forward and terminating inaninverted-V-shaped hook, Q This exerts aforce to depress the lantern,and counteracts any excessive motion imparted by the upper spring. Thespring Q, is similarly braced against excessive lateral movement by itsconvolutions lying against each other and against the wings M* in thesame manner as the spring P. Between the two sets of springs, one pairon each side, two pulling upward and two pulling downward, the entirelantern proper is supported elastically, so that the jolts andconcussions to which the carriage is subject are not communicated to thelantern. Furthermore, the positions in which the springs are placedinsures a parallel motion of the lantern, maintaining its propervertical position in all parts of its upward and downward movement. Theresult is to allow thelautern asufficiently free and yet parallelmotion. The wings Mi guard the lantern against being displaced too farlaterally. Under all ordinary conditions it rides on the springs withouttouching any other object.

I believe my case M, with its wings 31* and the sets of springs P Q,arranged as shown, may serve with other means than the clip L forattaching it to a carriage. I propose to provide in some cases an armreaching up from the case M M*, and equipped with a screw-clip or othermeans for attaching the lantern to the axle. I can attach two of mylanterns permanently or temporarily, one on each side of a carriage. Iprefer the whole as shown, and adapted to be used on the dashboard.

It is not desirable to brace the lantern against lateral motionabsolutely. The slight amount of lateral elasticity exhibited by mysprings P P Q Q is of advantage rather than the reverse; but it isimportant to guard the lantern against great movements laterally. Thisis effectually accomplished by the bracing of my coils P and Q againsteach other and against the wings M*, against which they are constantlypressed.

I claim as my invention- 1. The combination, with a lantern providedwith eyes D D", as shown, of springs arranged at the sides in two sets,one set, as P P P P, exerting a lifting force, and the other set, as Q QQ Q, exerting a depressing force, both braced against lateral yielding,and means for attaching the lantern to the dash-board of the carriage,substantially as herein specified.

2. The combination, with a lantern, as A B O D E. of easing M M* andsprings P Q, arranged in duplicate on each side, said springs havinghooks P Q, engaging with the lantern, and the clip L, screw N, and shoe0, adapted for attaching to the dash-board of a carriage, as hereinspecified.

In testimony whereofl have hereunto set my hand at New York city, this21st day of Feb ruary, 1887, in the presence of two subscribingwitnesses.
